Title:
【発明の名称】コントローラ、及びコントローラの出力範囲の決定方法
Document Type and Number:
Japanese Patent JP2682060
Kind Code:
B2
Abstract:
PURPOSE:To improve the versatility by providing a means which sets a control period and a means which determines an output range according to the set control period and adjusting the output range according to the difference between controlled systems which constitute the means respectively. CONSTITUTION:When an object 2 which is controlled by the fuzzy controller 1 is determined, the control period corresponding to the controlled system 2 is set in the fuzzy controller 1. The fuzzy controller 1 inputs the set control period and make the range of an output manipulated variable, i.e. the upper limit value PMAX and lower limit value NMAX extremely small according to the control period when the control period is <=100mus. When the control period is >=100mus, on the other hand, it is decided whether or not the period is short and when the period is <=1ms, the upper limit value and lower limit value of the manipulated variable are decreased. Thus, the corresponding proper output range is determined according to the control period and control operation by fuzzy reasoning is carried out in each period with the set control period and determined output range.
